clearCache() accepts $template, $cache_id and $compile_id. Each of them have no relation to one another. One $cache_id (or hierarchy thereof) could be used in multiple $templates and different $compile_ids thereof.
You can only optimize for one of them. The filesystem is not a database where you can query the column you like.

I don't see how you could improve the situation for everyone._________________Twitter

But if I turn off use_sub_dirs, will it still divide up the cache into subdirectories based on my cache groups?
